Charities are entities that put back all their profits into themselves. There are no shareholders and the charities success is driven by the do-go factor in its mission statement.
However, when writing a charity business plan with the aim of seeking funding, the most important factor a lender wants to see is that your charity is sustainable. This can be proven by building a financial model within your business plan that shows how after an initial round of fundraising, your charity will be able to support itself.
After that the most important to-do in fundraising is to ensure that you send your business plan to organisations who are likely to put money into your charity. For instance, If you're working with youth, make sure to apply for a grant through a fund that has been set up for charities helping youth.
